What is Voice Cloning?

AI voice cloning,  also known as voice synthesis or voice mimicry, is a technology that uses machine learning to simulate a specific person’s voice. This technology requires a certain amount of voice data to analyze and learn the unique vocal characteristics of the individual. Once trained, it can generate speech that sounds very similar to the original voice. Voice cloning models  are typically built using techniques from the field of deep learning, a branch of artificial intelligence. One common approach is to use a type of model known as a recurrent neural network (RNN), which is particularly well suited to dealing with sequential data like speech. One voice cloning application is Google’s Tacotron system. It can generate highly realistic speech in a range of voices. Other  voice cloning applications include Speechify  Voice Cloning  which is very user friendly. It brings generative AI, TTS, and human voice cloning to the masses. It’s worth noting that while voice cloning technology has many positive applications, it also raises ethical and legal issues related to consent, identity theft, and the potential for misuse in spreading misinformation or deception, such as in deepfake audio. As a result, it’s an area that requires careful regulation and oversight.

Frequently asked questions

Yes, it is  possible to clone a voice  with AI technology. This process is often referred to as “voice cloning” or “speech synthesis”.

The process typically involves training a deep learning model on a large amount of voice data from the person whose voice you want to clone. After the model has been adequately trained, it can generate speech that sounds very similar to the voice it was trained on.

However, it’s important to note that voice cloning technology raises serious ethical and legal concerns. It can be used maliciously for activities like fraud or disinformation campaigns, known as “deepfakes” for audio. There are ongoing discussions about how to regulate the use of this technology to prevent such misuse.

There are several AI technologies that can be used to generate a voice like yours, given sufficient data for training. Some notable ones are:

What is an AI Voice Generator?

An AI voice generator is a state-of-the-art technology that uses artificial intelligence (AI) to create voice recordings or speech that sounds human. These systems synthesize natural-sounding speech by analyzing large datasets of human voices through deep learning algorithms. AI voice generators can be used for various tasks, such as creating text-to-speech conversion solutions and voiceovers for movies and screen captures. They make producing high-quality audio content straightforward since they can imitate various accents, languages, and speech patterns. With its realistic and adaptable AI-generated voices, this technology revolutionizes sectors like accessibility services, media production, and content creation.

What is an AI Voice?

AI voice refers to a synthetic or computer-generated voice created using sophisticated algorithms and machine learning models. The AI voices' emulation of human voices makes speaking convincingly and naturally possible. Text-to-speech software, voice assistants, virtual CSRs, and content production are just a few of the industries they find use in. AI voices are flexible tools for information delivery, improving user experiences, and automating spoken communication chores since they can be tailored for various accents, languages, and tones.

How Do AI Voice Generators Work?

AI voice synthesizers use neural networks and deep learning techniques to mimic human speech. At first, these AI voice generators are trained on large datasets of human voice recordings to acquire phonemes, intonations, and speech patterns. After training, these models can anticipate the best phonetic and prosodic components to turn text input into synthetic voice. Pitch, tone, and tempo can all be changed to produce a variety of voices. Certain models (e.g., Synthesys) produce natural speech by combining phoneme sequences with text. With its natural-sounding synthetic voice, the output can be utilized for many purposes, such as voiceovers and text-to-speech. Here's a detailed rundown of how they function: Text processing — Written text is fed into the system at the start. This content may be presented in paragraphs, phrases, or even longer papers. Text analysis — The AI voice generator analyzes the text to determine its linguistic structure, including word order, punctuation, and grammar conventions. Sentence boundaries, parts of speech, and other linguistic components are also be identified at this step. Phonetic conversion — The AI then determines the text's phonetic representation. This entails dissecting words into their constituent phonemes, a language's smallest sound units. Voice selection — Selecting from various voices, dialects, and accents is the next option for the user, depending on the particular AI voice generator. The AI model that generates the voice can significantly impact the output's naturalness and quality. Natural Language Processing — The AI uses natural language processing techniques to comprehend semantics and context. This aids in choosing the proper tempo, stress, and intonation—all of which are essential for the generated speech to sound realistic. Voice synthesis — Combining phonetic components, prosody (intonation, rhythm, and pitch), and language context allows the AI to produce speech. The audio waveform is generated by deep learning models such as Transformer-based architectures, Convolutional Neural Networks (CNNs), and Recurrent Neural Networks (RNNs). Audio rendering — The audio waveform is then created from the synthesized speech. The digital audio data that can be played on speakers or headphones is represented by this waveform. Output — Delivering the created audio to the user is the last stage. This could take the shape of an audio file that can be downloaded, audio that can be streamed, or an application or service integration. Customization — customization is a key feature of modern AI voice generators. Users now have the ability to tweak elements like speech speed, pauses, pitch, and tone to better suit their preferences. These customization options have opened up new possibilities for users to personalize their AI-generated voices. Integration — integration is another exciting aspect of AI voice generators. These systems can seamlessly integrate into a range of applications, from virtual assistants and accessibility tools to e-learning platforms and content creation software. This integration capability makes AI-generated voices a valuable addition to various fields, enhancing the user experience in each of these areas. Over the past few years, AI voice generators have made significant advancements, resulting in remarkably natural-sounding speech. They have found their footing in diverse sectors, including education, entertainment, accessibility, and customer service. This progress has made synthetic speech that closely resembles human speech more accessible and adaptable than ever before.

How Long Does It Take To Synthesize Text to Speech?

Text complexity, speech synthesis engine performance, and text length are some variables that affect how long it takes to synthesize text into speech. Modern AI-based text-to-speech systems can produce speech for short to medium-length texts almost instantly, usually in a few seconds. However, the synthesis process may take a little longer—typically a few seconds to a minute—for longer and more complicated texts. Advances in AI technology have significantly shortened the time required for text-to-speech conversion, making it a quick and efficient process for various applications, including voice assistants and content production.

How is Voice Generation Time Calculated?

The text's intricacy, the AI voice model's quality, and the hardware's processing capacity affect how long it takes to generate an audio file. Since it's usually monitored in real-time, processing a minute's worth of voice creation takes roughly a minute. Dedicated gear and speedier CPUs, though, can expedite the procedure. Furthermore, cloud-based AI services could provide different processing speeds depending on server traffic. Longer texts and more complex voice models will also lengthen the generation time. In conclusion, real-time processing is the baseline, while text complexity, software, and hardware affect generation time.

Why Should I Use An AI Voice Generator Instead Of Hiring Voice Artists?

AI voice generators provide economical and practical options for content creation and voiceovers. They save time and money by offering instant access to various voices, languages, and accents. AI speech generators can produce content in minutes instead of paying professional voice actors; therefore, projects can be completed quickly. They also provide possibilities for pitch, tone, and pause adjustments, as well as speed, pronunciation, and emotions, resulting in adaptable and realistic-sounding results. Professional voice actors provide a personal touch, but AI voice generators are a realistic option for content creators seeking quality and ease, especially when working on tight deadlines or budgets.

Murf’s AI voice generator is trained on vast and diverse datasets of human speech that include various languages, accents, speech styles, and voice modulations. This enables the model to not only accurately replicate a wide range of vocal characteristics and nuances but also produce accurate and contextually relevant speech, making it useful for a wide range of applications.

Here's how the AI voice generation process happens:

• Text Processing: The AI system standardizes and analyzes the text input, identifying key linguistic elements such as sentence structure, word boundaries, and punctuation. It also interprets the context to accurately determine tone, emotion, and expressions, ensuring that the generated speech is both contextually relevant and emotionally appropriate.
• Phonetic Synthesis: The AI then breaks down each word into its phonetic components, accounting for variations in rhythm, intonation, and pronunciation based on the context, accent, and regional dialect.
• Voice Synthesis: Advanced neural networks synthesize the phonetic data into speech, generating a waveform that includes voice modulations like pitch and tone, ensuring a more dynamic and engaging output.
• Post-Processing : The audio is then refined with noise reduction and enhancement techniques to ensure clarity and quality.
• Output Delivery : The generated speech is finally converted into the desired format, making it ready for use in various applications.

How can Murf help Content Creators with AI Voiceovers? 

Content creators often struggle with the high costs and time-consuming processes involved in producing professional-quality voiceovers—be it hiring voice actors or spending hours editing audio—which leads to significant delays in content production.

Murf’s AI voice generator simplifies this process by providing an easy-to-use platform on which creators can generate studio-quality human-like voiceovers in minutes. Unlike typical AI-generated voices that sound monotonous and robotic, Murf’s lifelike voices sound 100% natural and can capture the nuances and tonalities of human speech. Simply enter your text in Murf’s text editor, choose an AI voice, and watch Murf produce natural, emotion-infused voiceovers in seconds. 

What are the Key Features of Murf AI Voice Generator?

Murf speech synthesis platform not only allows you to fine-tune the pitch, speed, pronunciation, pause, and emphasis of the generated audio to make it more compelling and natural but also enables you to incorporate media with the AI voiceover and change the voice styles. 

Control the tone in which your message is delivered by increasing or decreasing the ‘pitch’ of the AI voice between -50% and +50%. Lowering the pitch lends a sense of authority and seriousness (ideal for professional or educational content) while raising it makes the voice sound more lively and approachable (best fit for audiobooks and customer support content).

Use Murf’s ‘Pause’ feature to insert pauses of varying lengths into the narration, making it more natural and easier to follow. A pause before a crucial piece of information can heighten its importance and impact.

Use Murf’s ‘Speed’ feature to adjust how fast or slow the AI voice delivers the content. Speeding up the pace creates a dynamic and energetic feel while slowing down makes the content more easier to understand. 

Pronunciation

Achieve accurate word pronunciations using Murf’s custom pronunciation feature. You can either use alternative spellings or IPAs, ensuring that every word is conveyed clearly and accurately.

Voice styles

Need a warm and inviting tone for your eLearning videos? Or a confident and persuasive tone for your corporate training content? Murf supports a wide range of voice styles, enabling you to choose the one that best fits your content.

Background Music

Transform your AI-generated voice outputs effortlessly into captivating high-quality audio experiences with Murf’s integrated background music feature.

World-Level Emphasis

Need to highlight a crucial safety tip in a training module or deliver a punchline in your audiobook? With Murf’s new word-level emphasis feature, you can control the vocal stress and intonation of specific words or phrases, emphasizing any word just the way you want.

By adjusting the pace (moving the slide to the left or right side of a word) and pitch (moving the slide up or down the graph) of each word, you can subtly influence how your message is received—whether you need to convey urgency, add emotion, or ensure clarity.

Say It My Way

Want Murf’s AI-generated voice to perfectly match your unique style? With Murf’s ultimate customization feature, 'Say It My Way,' you can record your rendition of any line. Our model will capture your intonation, pace, and pitch, mirroring the exact length and emphasis of each word and pause in the generated speech. This allows you to maintain a consistent brand voice across all your projects, creating a more personalized audio experience.

Variability

Use Murf’s ‘Variability’ feature to generate multiple voiceover versions of any line, each with a different pitch and pace. You can choose the one that best fits your project’s tone and style without the need for extensive manual adjustments or re-recordings.

After ChatGPT and DALL-E, meet VALL-E - the text-to-speech AI that can mimic anyone’s voice

VALL-E can mimic someone’s voice saying anything with just a three-second recording.

Last year saw the emergence of artificial intelligence tools (AI) that can create images, artwork, or even video with a text prompt.

There were also major steps forward in AI writing , with OpenAI’s ChatGPT causing widespread excitement - and fear - about the future of writing.

Now, just a few days into 2023, another powerful use case for AI has stepped into the limelight - a text-to-voice tool that can impeccably mimic a person’s voice.

• DALL-E 2, Stable Diffusion, Midjourney: How do AI art generators work, and should artists fear them?

Developed by Microsoft, VALL-E can take a three-second recording of someone’s voice, and replicate that voice, turning written words into speech, with realistic intonation and emotion depending on the context of the text.

Trained with 60,000 hours worth of English speech recordings, it can deliver a speech in a "zero-shot situation," which means without any prior examples or training in a specific context or situation.

Introducing VALL-E in a paper published by Cornell University , the developers explained that the recording data consisted of more than 7,000 unique speakers.

• AI’s challenges in 2023: ChatGPT 4, combatting climate change and less bias

The team say their Text To Speech system (TTS) used hundreds of times more data than the existing TTS systems, helping them to overcome the zero-shot issue.

The tool is not currently available for public use - but it does throw up questions about safety, given it could feasibly be used to generate any text coming from anybody’s voice.

Microsoft betting big on AI

Its creators have, however, provided a demo , showcasing a number of three-second speaker prompts and a demonstration of the text-to-speech in action, with the voice correctly mimicked.

Alongside the speaker prompt and VALL-E’s output, you can compare the results with the "ground truth" - the actual speaker reading the prompt text - and the “baseline” result from current TTS technology.

• ChatGPT: Why the human-like AI chatbot suddenly has everyone talking

Microsoft has invested heavily in AI and is one of the backers of OpenAI, the company behind ChatGPT and DALL-E, a text-to-image or art tool.

The software giant invested $1 billion (€930 million) in OpenAI in 2019, and a report this week on semafor.com stated it was looking at investing another $10 billion (€9.3 billion) in the company.

Frequently Asked Questions

Can someone else use descript’s overdub tts to clone my voice.

No. When creating an Overdub Voice, Descript users must positively affirm their identity and give Descript their express consent to train and generate a synthesized version of their voice.

Voice-training data that does not include this Voice ID cannot be used to create an Overdub Voice. In other words, unless you specifically consent to Overdub Voice creation, Descript will not create your Overdub Voice.

We verify this consent by authenticating the audio file uploaded against our training script to ensure that the voice recorded belongs to the person submitting it.

Is Descript Text-to-Speech free?

Overdub text-to-speech is free on all Descript accounts. Pro accounts get an unlimited Overdub vocabulary.

Is there a difference between Overdub generated with the Pro subscription vs. a Creator or Free subscription?

Yes. While you can create a custom Voice on Overdub with any subscription,  Free and Creator plans are limited to a list of the 1,000 most common vocabulary words. Any words that are not on that list will be replaced with "jibber" or "jabber." To avoid this gibberish and gain access to the full vocabulary list, you can upgrade to the Pro subscription.

How can I improve the quality of my text-to-speech voice?

TTS voice quality relies on a number of factors, such as the quality of your microphone, background noise, and room surfaces. Check out our article on Overdub Voice Quality Tips for tips on how you can assure the best possible recording.

AI voice cloning is the process of generating synthetic speech that mimics a specific human voice. Using advanced machine learning algorithms, Resemble AI enables users to create realistic and personalized voice replicas for various applications.

What is the difference between Rapid Voice Clone and Professional Voice Clone?

Rapid Voice Clone and Professional Voice Clone are both state-of-the-art voice cloning technologies offered on our platform, designed to cater to different user needs and project scopes.

Rapid Voice Clone is all about speed and efficiency. It enables users to quickly create a custom voice clone using a small audio sample — as little as 10 seconds and up to 1 minute. The cloning process is swift, taking around a minute to complete. Currently, Rapid Voice Clone supports text-to-speech functionality, making it an excellent choice for projects that require fast turnaround times, like prototyping or content development where voice detail is secondary to speed.

Professional Voice Clone , on the other hand, is built for depth and nuance. It requires a longer audio sample, typically 10 minutes, and approximately an hour to create a voice clone. This clone captures the unique vocal characteristics of the original speaker, including their emotional nuances and expressiveness. Professional Voice Clone supports both text-to-speech and speech-to-speech functionalities and offers the ability to clone voices in various languages for Enterprise plan users. It is best suited for projects that demand high fidelity and detailed voice replication, such as professional-grade voiceovers, broadcasting, and customer engagement solutions where the quality of the voice clone is paramount.

In summary, the main differences lie in the time required to create the clone , the length of the audio sample needed , and the depth of voice replication and functionality . Your choice between Rapid and Professional Voice Clone should be guided by the specific requirements of your project, the level of detail needed, and the time frame for deployment.

My Voice is no longer my password —

Microsoft’s new ai can simulate anyone’s voice with 3 seconds of audio, text-to-speech model can preserve speaker's emotional tone and acoustic environment..

Benj Edwards - Jan 9, 2023 10:15 pm UTC

On Thursday, Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person's voice when given a three-second audio sample. Once it learns a specific voice, VALL-E can synthesize audio of that person saying anything—and do it in a way that attempts to preserve the speaker's emotional tone.

Its creators speculate that VALL-E could be used for high-quality text-to-speech applications, speech editing where a recording of a person could be edited and changed from a text transcript (making them say something they originally didn't), and audio content creation when combined with other generative AI models like GPT-3 .

Microsoft calls VALL-E a "neural codec language model," and it builds off of a technology called EnCodec, which Meta announced in October 2022. Unlike other text-to-speech methods that typically synthesize speech by manipulating waveforms, VALL-E generates discrete audio codec codes from text and acoustic prompts. It basically analyzes how a person sounds, breaks that information into discrete components (called "tokens") thanks to EnCodec, and uses training data to match what it "knows" about how that voice would sound if it spoke other phrases outside of the three-second sample. Or, as Microsoft puts it in the VALL-E paper :

To synthesize personalized speech (e.g., zero-shot TTS), VALL-E generates the corresponding acoustic tokens conditioned on the acoustic tokens of the 3-second enrolled recording and the phoneme prompt, which constrain the speaker and content information respectively. Finally, the generated acoustic tokens are used to synthesize the final waveform with the corresponding neural codec decoder.

Microsoft trained VALL-E's speech-synthesis capabilities on an audio library, assembled by Meta, called LibriLight . It contains 60,000 hours of English language speech from more than 7,000 speakers, mostly pulled from LibriVox public domain audiobooks. For VALL-E to generate a good result, the voice in the three-second sample must closely match a voice in the training data.

On the VALL-E example website , Microsoft provides dozens of audio examples of the AI model in action. Among the samples, the "Speaker Prompt" is the three-second audio provided to VALL-E that it must imitate. The "Ground Truth" is a pre-existing recording of that same speaker saying a particular phrase for comparison purposes (sort of like the "control" in the experiment). The "Baseline" is an example of synthesis provided by a conventional text-to-speech synthesis method, and the "VALL-E" sample is the output from the VALL-E model.

While using VALL-E to generate those results, the researchers only fed the three-second "Speaker Prompt" sample and a text string (what they wanted the voice to say) into VALL-E. So compare the "Ground Truth" sample to the "VALL-E" sample. In some cases, the two samples are very close. Some VALL-E results seem computer-generated, but others could potentially be mistaken for a human's speech, which is the goal of the model.

In addition to preserving a speaker's vocal timbre and emotional tone, VALL-E can also imitate the "acoustic environment" of the sample audio. For example, if the sample came from a telephone call, the audio output will simulate the acoustic and frequency properties of a telephone call in its synthesized output (that's a fancy way of saying it will sound like a telephone call, too). And Microsoft's samples (in the "Synthesis of Diversity" section) demonstrate that VALL-E can generate variations in voice tone by changing the random seed used in the generation process.

Perhaps owing to VALL-E's ability to potentially fuel mischief and deception, Microsoft has not provided VALL-E code for others to experiment with, so we could not test VALL-E's capabilities. The researchers seem aware of the potential social harm that this technology could bring. For the paper's conclusion, they write:

"Since VALL-E could synthesize speech that maintains speaker identity, it may carry potential risks in misuse of the model, such as spoofing voice identification or impersonating a specific speaker. To mitigate such risks, it is possible to build a detection model to discriminate whether an audio clip was synthesized by VALL-E. We will also put Microsoft AI Principles into practice when further developing the models."

The best AI voice generators: Convert text to human-like speech

Published on December 20, 2023

Whether you’re looking to emulate Arnold Schwarzenegger, David Attenborough, or even just yourself, computers can now emulate human voices to a very convincing degree. Just like how ChatGPT revolutionized the written medium, many video creators and social media personalities now rely on AI voice generators. The benefits are clear — adding a voice can make content come across as more expressive and personal. And with modern text-to-speech engines, you can fine-tune the delivery with different voices, customizable pitch, and even custom pronunciations. So without wasting any more time, here’s a list of the best AI voice generators available today.

1. ElevenLabs

If you’re looking for a text-to-speech product with the most diverse range of voices, you’ll be hard pressed to find one that competes with ElevenLabs . At its core, it offers AI voice generation with support for dozens of languages. But you can also go one step further with custom voices, which you can build from scratch by specifying the speaker’s gender, age, and other parameters.

ElevenLabs also allows you to clone existing voices, whether someone else’s or your own. The base tier allows you to clone a voice with audio clips as short as 60 seconds but you’ll need to upgrade to the Creator tier to create a more thorough replica of your voice. The latter costs $22 per month and also grants you roughly two hours of AI-generated generated audio. Another factor that makes ElevenLabs one of the best AI voice generators is that you can download your creations even on the free tier. You get 10,000 characters worth of audio generation per month without having to pay anything.

PlayHT claims that its AI voice generation works so well, it’s virtually impossible to distinguish from actual human speech. That certainly doesn’t hold true for all voices as a few I tested still sounded a bit robotic. But if you find the right one among the hundreds of choices, chances are that you’ll be happy with the results. PlayHT also recently showed off its new conversational text-to-voice AI model that sounds a lot more realistic, but it’s locked behind a waitlist for now.

As with most AI platforms, PlayHT requires you to subscribe to a paid plan beyond the initial free tier allowance. The minimum price of $31.2 per month certainly isn’t cheap, but the 600,000 generated words you get is a lot higher than rival platforms offer for that amount.

3. FakeYou: The best celebrity AI voice generator

If you’re looking for a celebrity AI voice generator, FakeYou performs remarkably well. The platform offers over 3,000 voices spread across categories such as television, video games, and musicians. Each voice has an associated quality rating, so you know how closely it matches the source. For example, Donald Trump’s voice had a rating of 3.5 — likely because it sounded a bit robotic. That said, the voice still matched the description and I can imagine the result would work fine for casual use cases. Arnold Schwarzenegger and Samuel L Jackson’s voice impressions are also rated higher.

FakeYou’s pricing plans are much simpler and cheaper than the competition, even though it’s one of the very few offering celebrity voices. But that’s mostly because you can only generate up to two minutes of audio at once. The cheapest paid plan, which will set you back $7 per month, grants just 30 seconds of audio and you may have to wait in a queue for each generation.

4. Speechify

In addition to standard text-to-speech, Speechify also offers an entire AI voice studio. The latter gives you a powerful timeline-based editor for voice overs, dubbing, and transcribing. As you can see in the above screenshot of a sample project, the interface is very intuitive and easy to use.

You start off with a blank project where you can add blocks of text, each with adjustable parameters like different voices, pauses, and custom pronunciations. This means you can create an audio clip with multiple voices talking to each other in a way that sounds organic and natural. You can also add in a background audio track and corresponding imagery to preview what your final audio clip will look and sound like. Speechify also includes two official celebrity voices to choose from at the moment, namely Snoop Dogg and Gwyneth Paltrow.

Speechify Studio’s free version doesn’t let you download any audio clips, but you can get a feel for the platform and decide whether it’s worth paying for. The cheapest premium plan comes in at $288 per year, or $24 per month. Luckily, if you only want an AI generated voice to read out your emails and websites, Speechify’s text-to-speech service is quite a bit more affordable at $139 per year.

If Speechify’s AI voice studio appeals to you, you’ll also want to check out Murf.AI . It offers a similar editing interface with customizable blocks of text and sliders for pitch and narration speed. You can also add emphasis to certain words or change their pronunciation from within the editor. You get 10 minutes of audio generation as a free user, with full access to the editor and voices. Like the others on this list, you’ll have to fork over for a paid plan if you want to download the clips for your own use.

6. Acoust AI

If you’re looking for a basic AI voice generator with a generous free trial, I’d recommend checking out Acoust . It’s a relatively new company, so not much is known about how it works behind the scenes. That aside, though, it works remarkably well with dozens of languages in a variety of languages on offer.

When you sign up for an account, you get 15 minutes’ worth of voice generation for free. The interface is simple to use, but is simultaneously quite feature-rich. You can import text from webpages, your own speech file, documents, or even ask the GPT-powered AI writer to come up with the source material. Acoust also supports adding background music and custom pronunciations.

7. Tortoise-TTS: The best free AI voice generator

So far, every single AI voice generator on this list requires a monthly payment of at least a few dollars per month. Luckily, that’s not your only option if you own or have access to a powerful computer. Tortoise is regarded as the best open-source text-to-speech programs that you can download and run on your own PC with just a few commands. Be warned that converting text to natural-sounding speech is a fairly resource intensive process, so you may have to wait longer between each generation if you use slower hardware. Tortoise’s developers have put together a demo page in case you’d like to check out what it’s capable of.

Tortoise requires an Nvidia GPU or an Apple Silicon-based Mac, so it goes without saying that you’ll need a fairly recent computer. But even if you don’t meet that condition, you can use a cloud service like Google Collaboratory for free. Another open source project, titled TTS Generation WebUI , offers a one-click setup process through Google Collab that eliminates the need for any command line work whatsoever. Simply head on over to the project’s GitHub page and click on the Google Collab button to get started.

We’ve also used Google Collab in conjunction with another free project to run a chatbot in the past, in case you’re looking for a open-source alternative to ChatGPT .

Voice   Generator

This web app allows you to generate voice audio from text - no login needed, and it's completely free! It uses your browser's built-in voice synthesis technology, and so the voices will differ depending on the browser that you're using. You can download the audio as a file, but note that the downloaded voices may be different to your browser's voices because they are downloaded from an external text-to-speech server. If you don't like the externally-downloaded voice, you can use a recording app on your device to record the "system" or "internal" sound while you're playing the generated voice audio.

Want more voices? You can download the generated audio and then use voicechanger.io to add effects to the voice. For example, you can make the voice sound more robotic, or like a giant ogre, or an evil demon. You can even use it to reverse the generated audio, randomly distort the speed of the voice throughout the audio, add a scary ghost effect, or add an "anonymous hacker" effect to it.

Note: If the list of available text-to-speech voices is small, or all the voices sound the same, then you may need to install text-to-speech voices on your device. Many operating systems (including some versions of Android, for example) only come with one voice by default, and the others need to be downloaded in your device's settings. If you don't know how to install more voices, and you can't find a tutorial online, you can try downloading the audio with the download button instead. As mentioned above, the downloaded audio uses external voices which may be different to your device's local ones.

You're free to use the generated voices for any purpose - no attribution needed. You could use this website as a free voice over generator for narrating your videos in cases where don't want to use your real voice. You can also adjust the pitch of the voice to make it sound younger/older, and you can even adjust the rate/speed of the generated speech, so you can create a fast-talking high-pitched chipmunk voice if you want to.

Note: If you have offline-compatible voices installed on your device (check your system Text-To-Speech settings), then this web app works offline! Find the "add to homescreen" or "install" button in your browser to add a shortcut to this app in your home screen. And note that if you don't have an internet connection, or if for some reason the voice audio download isn't working for you, you can also use a recording app that records your devices "internal" or "system" sound.

Installation

Hardware requirements.

Mimic 3 was designed to run on the Raspberry Pi 4 (64-bit OS), but will also run on other platforms:

AMD/Intel-based desktops/laptops

Very fast on Ryzen 9 5950X, RTF less than 0.05

Raspberry Pi 3/4 and Zero 2 with 64-bit Pi OS

Usable on Pi 4, RTF around 0.5

Raspberry Pi 1/2/3/4 and Zero 2 with 32-bit Pi OS

Slow on Pi 3, RTF around 1.3

Real-Time Factor

The performance of a text to speech system is often measured by its real-time factor (RTF). This is the ratio of how long it takes to generate audio to how long the audio is when spoken. In general, lower is better for RTF.

An RTF of 1 means that it took one second of compute time to generate one second of spoken audio. An RTF of 0.5 is better than 1, however, since the same second of spoken audio now only took half a second to generate.

Enable the plugin in your mycroft.conf file:

or you can manually add the following to mycroft.conf with mycroft-config edit user :

Plugin Configuration Options

A range of configuration options can be added to customize the Mimic 3 TTS output, for example:

voice - a Voice Key defining the TTS model to be used. You can find a list of all available Voice Keys on Github .

speaker - for multi-speaker voice models, the default speaker to be used. To hear all the speakers see https://mycroft.ai/mimic-3/

length_scale - controls how fast the voice speaks the text. A value of 1 is the speed of the training dataset. Less than 1 is faster, and more than 1 is slower.

noise_scale - the amount of noise added to the generated audio (0-1). Can help mask audio artifacts from the voice model. Multi-speaker models tend to sound better with a lower amount of noise than single speaker models.

noise_w - the amount of noise used to generate phoneme durations (0-1). Allows for variable speaking cadance, with a value closer to 1 being more variable. Multi-speaker models tend to sound better with a lower amount of phoneme variability than single speaker models.

As a web server

In a screen reader

Voices in Mimic 3 are keyed by a name with specific parts. These parts include the voice's language, region, training dataset, quality level, and speaker.

The default voice is en_UK/apope_low

Voice models are automatically downloaded from Github and stored in ${HOME}/.local/share/mycroft/mimic3 (technically ${XDG_DATA_HOME}/mycroft/mimic3 ). You can also manually download them .

Command-Line Interface

Basic synthesis.

The mimic3 command can be used to synthesize audio on the command line:

where <voice> is a voice key like en_UK/apope_low . <TEXT> may contain multiple sentences, which will be combined in the final output WAV file. These can also be split into separate WAV files .

A subset of Speech Synthesis Markup Language, or SSML , is available through the command line and web interface. SSML allows you to fine tune your output.

SSML even lets you mix and match languages:

If your SSML contains <mark> tags, add --mark-file <file> to the command-line and use --interactive mode. As the marks are encountered, their names will be written on separate lines to the file:

The following SSML tags are supported:

<speak> - wrap around SSML text

lang - set language for document

<s> - sentence (disables automatic sentence breaking)

lang - set language for sentence

<w> / <token> - word (disables automatic tokenization)

<voice name="..."> - set voice of inner text

voice - voice key

<prosody attribute="value"> - change speaking attributes

Supported attribute names:

volume - speaking volume

number in [0, 100] - 0 is silent, 100 is loudest (default)

+X, -X, +X%, -X% - absolute/percent offset from current volume

one of "default", "silent", "x-loud", "loud", "medium", "soft", "x-soft"

rate - speaking rate

number - 1 is default rate, < 1 is slower, > 1 is faster

X% - 100% is default rate, 50% is half speed, 200% is twice as fast

one of "default", "x-fast", "fast", "medium", "slow", "x-slow"

<say-as interpret-as=""> - force interpretation of inner text

number - one of "cardinal", "ordinal", "digits", "year"

date - string with "d" (cardinal day), "o" (ordinal day), "m" (month), or "y" (year)

<break time=""> - Pause for given amount of time

time - seconds ("123s") or milliseconds ("123ms")

<sub alias=""> - substitute alias for inner text

<phoneme ph=""> - supply phonemes for inner text

See phonemes.txt in voice directory for available phonemes

Phonemes may need to be separated by whitespace

SSML <say-as> support varies between voice types:

Character-based voices do not currently support <say-as>

epitran based voices do not currently support <say-as>

If your text is very long, and you would like to listen to it as its being synthesized, use --interactive mode:

Each input line will be synthesized and played (see --play-program ). By default, 5 sentences will be kept in an output queue, only blocking synthesis when the queue is full. You can adjust this value with --result-queue-size .

If your long text is fixed-width with blank lines separating paragraphs like those from Project Gutenberg , use the --process-on-blank-line option so that sentences will not be broken at line boundaries. For example, you can listen to "Alice in Wonderland" like this:

Multiple WAV Output

With --output-dir set to a directory, Mimic 3 will output a separate WAV file for each sentence:

By default, each WAV file will be named using the (slightly modified) text of the sentence. You can have WAV files named using a timestamp instead with --output-naming time . For full control of the output naming, the --csv command-line flag indicates that each sentence is of the form id|text where id will be the name of the WAV file.

You can adjust the delimiter with --csv-delimiter <delimiter> .

Additionally, you can use the --csv-voice option to specify a different voice or speaker for each line:

The second contain can contain a #<speaker> or an entirely different voice!

Interactive Mode

With --interactive , Mimic 3 will switch into interactive mode. After entering a sentence, it will be played with --play-program .

Use CTRL+D or CTRL+C to exit.

Noise and Length Settings

Synthesis has the following additional parameters:

--noise-scale and --noise-w

Determine the speaker volatility during synthesis

0-1, default is 0.667 and 0.8 respectively

--length-scale - makes the voice speaker slower (> 1) or faster (< 1)

Individual voices have default settings for these parameters in their config.json files (under inference ).

List Voices

Cuda acceleration.

If you have a GPU with support for CUDA, you can accelerate synthesis with the --cuda flag. This requires you to install the onnxruntime-gpu Python package.

Using nvidia-docker is highly recommended. See the Dockerfile.gpu file in the parent repository for an example of how to build a compatible container.

A small HTTP server is available for serving multiple clients. This is faster than the command-line interface since voice models only need to be loaded once.

Running the Server

This will start a web server at http://localhost:59125

To access the web server from a different device, run mimic3-server --host 0.0.0.0 (you can also change the port with --port ).

Some other useful arguments to mimic3-server :

--preload-voice <VOICE_KEY> - loads a voice model at startup instead of on first use

--cache-dir <DIRECTORY> - caches WAV files in <DIRECTORY> (uses system temporary directory if no <DIRECTORY> )

--num-threads <THREADS> - use more than one thread of inference, increasing throughput for multiple clients

See mimic3-server --help for more options.

POST text or SSML and receive WAV audio back

Use ?voice= to select a different voice/speaker

Set Content-Type to application/ssml+xml (or use ?ssml=1 ) for SSML input

/api/voices

Returns a JSON list of available voices

An OpenAPI test page is also available at http://localhost:59125/openapi

Using nvidia-docker is highly recommended. See the Dockerfile.gpu for an example of how to build a compatible container.

Running the Client

Assuming you have started mimic3-server and can access http://localhost:59125 , then run:

If your server is somewhere besides localhost , use mimic3 --remote <URL> ...

See mimic3 --help for more options.

MaryTTS Compatibility

Use the Mimic 3 web server as a drop-in replacement for MaryTTS , for example with Home Assistant .

Make sure to use a Mimic 3 voice key like en_UK/apope_low instead of a MaryTTS voice name:

Speech Dispatcher

WORK IN PROGRESS: This has not been tested on a broad range of systems. Some debugging may be required.

Mimic 3 can be used with the Orca screen reader for Linux via speech-dispatcher .

After installing Mimic 3 , start the web server . Next, make sure you have speech-dispatcher installed:

Create the file /etc/speech-dispatcher/modules/mimic3-generic.conf with the contents:

You will need sudo access to do this. Make sure to change /path/to/mimic3 to wherever you installed Mimic 3. Note that the --remote option is used to connect to a local Mimic 3 web server (use --remote <URL> if your server is somewhere besides localhost ).

To change the voice later, you only need to replace en_UK/apope_low .

Next, edit the existing file /etc/speech-dispatcher/speechd.conf and ensure the following settings are present:

Restart speech-dispatcher with:

and test it out with:

Systemd Service

To ensure that Mimic 3 runs at boot, create a systemd service at $HOME/.config/systemd/user/mimic3.service with the contents:

Make sure to change /path/to/mimic3-server to wherever you installed Mimic 3.

Refresh the systemd services:

Now try starting the service:

If that's successful, ensure it starts at boot:

Verify the web server is running by visiting http://localhost:59125

Downloading Voices

Mimic 3 automatically downloads voices when they're first used, but you can manually download them too with mimic3-download .

For example:

will download all U.S. English voices to ${HOME}/.local/share/mycroft/mimic3/voices .

You can list the available voices with --voices :

Voice models are stored locally in your home directory:

Some voices even have multiple speakers. This one has over one hundred .

See mimic3-download --help for more options.

How It Works

Mimic 3 uses the VITS , a "Conditional Variational Autoencoder with Adversarial Learning for End-to-End Text-to-Speech". VITS is a combination of the GlowTTS duration predictor and the HiFi-GAN vocoder .

Our implementation is heavily based on Jaehyeon Kim's PyTorch model , with the addition of Onnx runtime export for speed.

Phoneme Ids

At a high level, Mimic 3 performs two important tasks:

Converting raw text to numeric input for the VITS TTS model, and

Using the model to transform numeric input into audio output

The second step is the same for every voice, but the first step (text to numbers) varies. There are currently four implementations of step 1, described below.

gruut Phoneme-based Voices

Voices that use gruut for phonemization.

gruut normalizes text and phonemizes words according to a lexicon, with a pre-trained grapheme-to-phoneme model used to guess unknown word pronunciations.

eSpeak Phoneme-based Voices

Voices that use eSpeak-ng for phonemization (via espeak-phonemizer ).

eSpeak-ng normalizes and phonemizes text using internal rules and lexicons. It supports a large number of languages, and can handle many textual forms.

Character-based Voices

Voices whose "phonemes" are characters from an alphabet, typically with some punctuation.

For voices whose orthography (writing system) is close enough to its spoken form, character-based voices allow for skipping the phonemization step. However, these voices do not support text normalization, so numbers, dates, etc. must be written out.

Epitran-based Voices

Voices that use epitran for phonemization.

epitran uses rules to generate phonetic pronunciations from text. It does not support text normalization, however, so numbers, dates, etc. must be written out.

Components of a Voice Model

Voice models are stored in a directory with a specific layout:

<language>_<region> (e.g., en_UK )

<voice-name>_<quality> (e.g., apope_low )

ALIASES - alternative names for the voice, one per line (optional)

config.json - training/inference configuration (see code for details)

generator.onnx - exported inference model (see ids_to_audio method in voice.py )

LICENSE - text, name, or URL of voice model license

phoneme_map.txt - mapping from source phoneme to destination phoneme(s) (optional)

phonemes.txt - mapping from integer ids to phonemes ( _ = padding, ^ = beginning of utterance, $ = end of utterance, # = word break)

README.md - description of the voice

SOURCE - URL(s) of the dataset(s) this voice was trained on

VERSION - version of the voice in the format "MAJOR.Minor.bugfix" (e.g. "1.0.2")

Mimic 3 is available under the AGPL v3 license

Process some Speech Synthesis Markup Language tags in the text above.

Controls how fast the voice speaks the text. A value of 1 is the speed of the training dataset. Less than 1 is faster, and more than 1 is slower.

The amount of noise added to the generated audio (0-1). Can help mask audio artifacts from the voice model. Multi-speaker models tend to sound better with a lower amount of noise than single speaker models.

The amount of noise used to generate phoneme durations (0-1). Allows for variable speaking cadance, with a value closer to 1 being more variable. Multi-speaker models tend to sound better with a lower amount of phoneme variability than single speaker models.

This website hosts a beta version of Mimic 3 , Mycroft's newest text to speech system developed for the Mark II . When released, Mimic 3 will be available to run locally on Linux systems like the Raspberry Pi 4.

We are interested in hearing your feedback , especially on the non-English language voices! We hope to improve the quality and accuracy of every voice over time 😀

• Mimic 3 is running without any GPUs (CPU only)
• This website is shared among all beta reviewers
• Caching is disabled, so each request is synthesized fresh

Privacy: this website does not store the text you send or the audio that is synthesized.
